Solar & Off-Grid Calculators
Essential calculators for solar energy and off-grid living. Calculate panel tilt angles, battery bank sizing, wire gauges, inverter sizing, ROI, and more.
Solar Panel Tilt Angle Calculator
Calculate the optimal tilt angle for solar panels based on your latitude and season to maximize energy production.
Battery Bank Sizing Calculator
Calculate how many batteries you need for your off-grid system based on daily energy consumption, voltage, and depth of discharge.
Off-Grid Runtime Calculator
Calculate how long your backup power system can run specific appliances during a power outage.
DC Wire Gauge Calculator
Calculate the correct wire gauge for DC circuits to minimize voltage drop and prevent overheating. Essential for solar and automotive wiring.
Inverter Size Calculator
Calculate the required inverter size by adding up all appliance wattages with a safety margin for surge power.
Sun Peak Hours Calculator
Look up average peak sun hours for your location to estimate solar panel energy production throughout the year.
Solar ROI Calculator
Calculate the return on investment for a solar panel system. Determine how many years until your system pays for itself.
DC Power Calculator (Amps ↔ Watts)
Convert between amps, watts, and volts for DC circuits. Simple power calculation for batteries and solar systems.
Generator Fuel Consumption Calculator
Calculate how long a generator can run on a tank of fuel based on load, fuel type, and tank capacity.
Rainwater Collection Calculator
Calculate how much rainwater you can collect based on your roof area, rainfall, and collection efficiency.
